Why does my reining horse run through the bridle before stopping?

A reining horse that runs through the bridle — ignoring or overpowering rein contact rather than rating and stopping in response to it — is either too strong in the face from training that relied on sustained rein pressure, too anxious and forward to respond to the bridle under the excitement of the rundown, or genuinely lacking the body control and rate response that the stop requires as a foundation. Each cause produces the same symptom but requires a different primary correction. A horse that has become strong in the face from over-use of the rein has learned to lean against constant contact because it is always present whether the horse is doing something right or wrong. The rein has lost its communication value through overuse, and pulling harder to produce the stop simply confirms that the horse should keep pushing against the pressure. The correction is removing constant rein contact and re-establishing a cue-and-release system where the rein means something specific rather than functioning as a continuous restraint. A horse that is too anxious in the rundown — too forward, too excited, too mentally elevated to respond to the bridle — needs its overall energy level addressed before the stop can be correct. Rate work, frequent downward transitions, and slow work that reduces the horse's arousal around the rundown are the primary tools. A horse that lacks basic body control and rate will run through the bridle because the stop has no foundation to stand on — the rate response must be confirmed at the walk, trot, and slow lope before it is expected during a gallop toward the end of the pen. Building softness and rating response at slow speeds first gives the horse the tools the stop requires.
